The TR-35MS from Thermo Fisher Scientific is a silphenylene-based phase ideal for all GC/MS applications. The column is particularly suited for applications which require a high temperature phase but need more polarity than a 5% phenyl column. The TR-35MS can be used in combination with a 5% phenyl column as a confirmation column.
The TR-35MS column is a universal column used in a wide range of applications from environmental semi-volatile methods to food and fragrance applications. If the GC/MS is exposed to many varied methods then this is the preferred column of choice for the instrument. This phase is extremely low bleed with a maximum operating temperature of 370°C.
